Something like that happens to me... my KS7500 shows the 1231.1 version, the lastest version at the site says the same. Connecting the soundbar to an HDMI port fixed it for me.
I think that - at least in TV and soundbars-, Samsung as a brand is overpriced and they are masters of programmed obsolescence, retiring support and improvements in not so old models.
The lack of Homekit support for 2016 Tizen TV's, and the fact that I had to import overseas the rear speakers set for my k550 soundbar because the only compatible model is now discontinued (funny, because the soundbar is still being sold in stores, and the purchase operation increased the price from about 100€ to almost 300€, because A LOT OF PEOPLE in my situation is demanding the accessory) . Has killed my trust in the company.
I have not said yet that my TV is a 55", a 1500€ Series 7 unit with no more than 3 years old which has been showing a couple of bright spots in a side for the last 2 years.
Also for the rear speakers... had to pass the wires thru a amplifier because the volume was low and barely noticeable. Great news after spending a lot of money. Don't even think that the soundbar is offering a superb sound, only the subwofer sounds great (and there it goes another 300€).
Ah, and their super closed and anti-Apple ecosystem. They never launched an iOS app for the speakers, like they did for Android.
After a washing machine, fridge, soundbar, rear speakers and 2 TVs, I'm not going to get more Samsung stuff. Don't want to think if one day my fridge or washing machine stopped working...
